Learning Objectives

Indicator: 3.1.1.LI.3 - Explain the formation of the sun, planets and stars.

By the end of the lesson, learners can:

Describe the nebular hypothesis as the leading scientific explanation for the formation of the sun, planets and stars.
Sequence the stages of star formation from a collapsing molecular cloud to a main-sequence star.
Explain how the solar system formed from a rotating cloud of gas and dust, including the roles of gravity and angular momentum.
Distinguish between the formation of the sun and planets on one hand, and the formation of other stars on the other.
Use scientific vocabulary (nebula, protostar, main sequence, accretion, solar nebula) correctly when explaining cosmic formation processes.
